Chapter 3: Architectural Methods of Malware Defense

Introduction to architectural methods of malware defense

Like any defense malware defense should be multi-level. AV/antispyware scanners which are dominant type of spyware protection are just one element of such defense.

There is general law that the more particular organism is adapted to particular environment, the more sensitive it is to even slightest changes of this environment. This law holds for malware as they are highly specilised types of software.

Exploration of this law in historical context was one of the main reasons of writing this book. The key idea here is that as change of environment is often deadly for malware we need preemptlivly intoriduce such changes. This allows to exploit fuinadamental weakness of malware: like any highly specialized organism it is very sensitive to slightest changes in OS or in case they use TCP/IP, to the network configuration.

Also monocultures are more susspetable to deseases. History of crops that attect more powerful parasites trhat eventually became resistant to particular herbisites is replaed in software context with malware and anti-viruese. In a way malware is a result of PC monoculture with Windows as the dominant system. The fact that this is Windows not Linux does not matter -- for any other dominant Os there will be enough reserach to uncover flows that can be exploited in malware.

For any type of malware the malware author makes multiple implisit choices about the enviroment as he wishes to expoit what is some minor lows of this enviroment for propotagtion. That means that a sight change (for example patch) might kill the ability of particular malware to propogate.

But things are more complex that that. Out of infinine number of Windows comfigrations, the malware author needs to orient himself on the most common confiuguration. Any move "left or right" from this "most common" Windows environment means that malware will be unable itether to infect PC of propogate or both.

 

And the most important are architectural methods, the methods which change architecture of your enterprise or home network and Windows OS in such a way as to make propagation of malware more difficult and make some element of your environment different from the "most common case" on which malware authors orient.

The most important malware propagation vector now is picking up rogue site in Internet search engine, typically Google. Reading and acting upon a rogue email is a distant second. Again those are two are the most popular. Many others exists.

That means that offloading your Web browsing activities to a different platform or "disposable Pc" or different type of CPU provides instant and very effective defense against all existing and still non-written types of Windows malware.

When Linux enthusiasts claim that their beloved OS is less malware friendly then Windows they are only partially wrong ;-).  Currently there are very few malware that target Linux. But this is mostly die to the fact that Windows as a dominant PC OS attacks lion share of malware. Should the situation reverse and Linux became dominant desktop OS with 80% or more market share I am sure there will be plenty malware for Linux.

The fact that Windows will be available on ARM chips in the fall of 2012 means that you can use this methods with relatively minor expense.
